Abstract

A compound transmission (12) including main and auxiliary transmission sections (14,15) having several pin-type, double-acting, self-energizing synchronizer mechanisms (60,62,84). The several synchronizer mechanisms are configured to provide higher self-energizing forces for higher speed reduction ratio gears than for lower speed reduction gears, and to provide higher self-energizing forces for downshifts than for upshifts. The self-energizing forces are provided by improved self-energizing ramp surfaces (29e,29f,29g,29h and (111a,111b,111c,111d) formed in external splines 29 of a shaft 28 and in internal teeth extending radially inward from a shift flange 110. The shift flange carries improved pre-energizer and neutral centering assemblies (120) axially retained by end surfaces (102a,104a) of jaw clutch member (102,104).
